31250903 ÷ 904 
We want to divide 31250903 by 904.

Step 1:
904 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 904

Let's proceed to step 2:
31 divided by 904 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 904

Advancing to step 3:
312 divided by 904 is 0 with a remainder of 312.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 312 to get 312.
Grab the next digit (5) from the dividend, add it to 312, then carry on: 3125 / 904

Going ahead to step 4:
If we divide 3125 by 904, we get 3 and a remainder of 413.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2712 from 3125 and we're left with 413.
Take the next digit (0) from the dividend and append it to 413, then repeat: 4130 / 904

Step 5:
When dividing 4130 by 904, we get 4 with a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 3616 from 4130, we get 514.
Fetch the next digit (9) from the dividend, attach it to 514 and continue: 5149 / 904

Advancing to step 6:
The number 904 fits into 5149 5 times, leaving a remainder of 629.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
Deduct 4520 from 5149 and we're left with 629.
Include the next digit (0) from the dividend after 629, then repeat: 6290 / 904

Step 7:
If we divide 6290 by 904, we get 6 and a remainder of 866.
Record the quotient 6 as the next digit in the result. 
Result so far: 3456.0
Deduct 5424 from 6290 and we're left with 866.
Include the next digit (3) from the dividend after 866, then repeat: 8663 / 904

Going ahead to step 8:
When dividing 8663 by 904, we get 9 with a remainder of 527.
Put 9 as the next digit of the answer. 
Result so far: 34569.0
If we subtract 8136 from 8663, we get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Let's proceed to step 9:
904 can be fit into 5270 5 times, resulting in a remainder of 750.
The number 5 becomes the next digit in our result. 
Result so far: 34569.5
Subtract 4520 from 5270 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 10:
904 goes into 7500 8 times with a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 34569.58
If we subtract 7232 from 7500, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 11:
The number 904 fits into 2680 2 times, leaving a remainder of 872.
The next digit of our result is 2. 
Result so far: 34569.582
If we take 1808 away from 2680, we end up with 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Let's proceed to step 12:
If we divide 8720 by 904, we get 9 and a remainder of 584.
Write down 9 as next digit of the result. 
Result so far: 34569.5829
If we take 8136 away from 8720, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 13:
If we divide 5840 by 904, we get 6 and a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 34569.58296
Subtracting 5424 from 5840 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 14:
4160 divided by 904 is 4 with a remainder of 544.
Use 4 as the next digit of our solution. 
Result so far: 34569.582964
Subtract 3616 from 4160 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 15:
If we divide 5440 by 904, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 34569.5829646
Deduct 5424 from 5440 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 16:
If we divide 160 by 904, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 34569.5829646
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 34569.5829646 with a remainder of 1.6e-07.
